Lanthanide Complexes of Aminopolycarboxylates Reveal Deuteration of Aminoacetate Carbons In Alkaline Aqueous Media Hydrogen isotope exchange at aminoacetate carbons is facilitated in lanthanide aminopolycarboxylate complexes in NaOD D2O solution. Ionic radius-dependent yields revealed Lu3+ being choice. NMR and Raman spectroscopies evidence yield and selectivity while theoretical calculations help understanding the mechanism.

Trivalent f-elements in human saliva: a comprehensive speciation study by time-resolved laser-induced fluorescence spectroscopy and thermodynamic calculations - Dalton Transactions (RSC Publishing)

| Chemistry World Verified
In the case of oral ingestion of radioactive contaminants, the first contact medium is saliva in the mouth. To gain a first insight into the interaction of radioactive contaminants in human saliva, the speciation of curium (Cm( )) and europium (Eu( )), i.e., trivalent f-elements, was investigated in different salivary media with time-resolved laser-induced fluorescence spectroscopy (TRLFS).
